Questions about Challenges regarding Autism

Hi! I am developing an app focused on helping people with autism improve cognitive empathy through using LLM to help users respond empathetically to pretend text conversations. However, I've had little experience with autism before.

I'm wondering if you could share any advice on whether the aim of my app is really relevant for autistic people, what I need to consider for making this app autism-friendly (for example, I think some autistic people do not like bright light or noise?), or any other challenges you face in daily life that you also wish this app to address. Thank you!
